וְעֵ֤לָּא מִנְּהוֹן֙ סָרְכִ֣ין תְּלָתָ֔א דִּ֥י דָנִיֵּ֖אל חַֽד־מִנְּה֑וֹן דִּֽי־לֶהֱוֺ֞ן אֲחַשְׁדַּרְפְּנַיָּ֣א אִלֵּ֗ין יָהֲבִ֤ין לְהוֹן֙ טַעְמָ֔א וּמַלְכָּ֖א לָֽא־לֶהֱוֵ֥א נָזִֽק׃

and over them three presidents, of whom Daniel was one; that these satraps might give account unto them, and that the king should have no damage.
